Definitions

  • the invention relates to a suction pile, a foundation made from one or more suction piles and an offshore structure, e.g. an above the sea water projecting wind turbine, resting on a foundation comprising one or more suction piles.
  • a suction pile is a thin walled steel sleeve or pipe or cylinder, which cylinder is closed at its longitudinal top end by a bulkhead or different sealing means and which cylinder is sealingly located on the subsea bottom with the open end opposite the bulkhead since this open end penetrates the subsea bottom due to the weight of the suction pile.
  • the cavity also called suction space
  • suction space delimited by the cylinder and the bulkhead is sealed by the subsea floor such that vacuum or suction can be generated by removing water from within the suction space such that a resulting force tends to force the suction pile deeper into the subsea floor.
  • the creation of the suction can be with the aid of a suction source, such as a pump, being on, or close to or at a distance from the suction pile and connected to the suction space.
  • the applied level of the suction can be e.g. at least substantially constant, smoothly increase or decrease or else pulsate, for which there are convenient means.
  • the suction pile can easily be removed by creating an overpressure within the suction space, e.g. by pumping in (sea) water.
  • a self installing platform applying suction piles is known from e.g. WO99/51821 (SIP1) or EP-A-1 101 872 (SIP2) of the present inventor.
  • WO 02/088.475 (Suction Pile Technology, SIP3) discloses a tower carrying a wind turbine at the top and suction piles as foundation.
  • suction piles One of the benefits of suction piles is that a marine structure can be designed to be self foundating or self installing by providing it with one or more suction piles. So the hoisting device and the plant for installing the foundation, e.g. hammering device, can be eliminated.
  • the structure is provided with one or more suction piles, removal after use is made easier in that by pressing out the suction pile, the anchoring of the structure to the underwater bottom can be removed.
  • each suction pile has one or more of: a diameter of at least 5 metres; a height of at least 5 metres; a wall thickness of at least 1 centimetre; the longitudinal axis of the suction pile and the relevant supporting leg (of the upper structure to be supported by the suction pile) are substantially in line or eccentric.
  • Suction piles may suffer from scouring of the seabed around them. To avoid scouring it is known to cover the seabed by a layer of loose rocks or a mat of artificial frond.
  • piles installed by hammering several proposals for extendable or unfoldable seabed covering devices mounted to the pile prior to hammering the pile into the seabed are known. Viz. e.g. GB2024901A , EP2767637A1 or GB1537238A .
  • suction piles Compared to piles installed by pile-driving, suction piles have a diameter at least twice the pile diameter and a length not more then half the pile length. Thus the technical field of suction piles differ largely from pile-driven piles for an offshore foundation.
  • the object of the invention is versatile. In an aspect the reliability of the foundation is improved. In an aspect the installation of the foundation is made quicker and/or cheaper.
  • the object is obtained by providing the suction pile, preferably near its top bulkhead and possibly at a level spaced below the level of this bulkhead (viewed in the upright condition of the suction pile) with an extendable or unfoldable seabed scour protection device (SSPD) comprising a web (also called screen or mat or cover like device or sheet or foil or cover device or cover material) to cover or screen, when extended or unfolded, the seabed adjacent the suction pile to avoid scouring.
  • SSPD seabed scour protection device
  • This SSPD is preferably mounted to the suction pile before the suction pile is lowered onto the seabed, e.g. while the suction pile completely or partly projects above the water or is located on a vessel or at an on shore location.
  • the SSPD is mounted at such level that it remains above the seabed once the suction pile is installed into the seabed.
  • the SSPD is designed to be unfolded by a translating movement of one of its edges, preferably a free edge (e.g. the edge that is wound onto the roll last, which edge could also be called leading edge), e.g. a movement similar to unwinding a rolled web by pulling at its free end.
  • a pushing means e.g. bearing against the suction pile.
  • unfolding can be obtained by pulling at the leading edge with a pulling means, e.g. remote from the suction pile, e.g. a cable e.g. extending from a vessel, to unroll the screen.
  • unfolding can be gravity powered, e.g. due to descending of the SSPD or part of it.
  • the SSPD when retracted or folded or collapsed, is preferably rolled or creased or pleated or differently stored to a small dimension, to preferably have an extension less than 10% or 20% compared to its extension when unfolded.
  • the SSPD unfolds or extends or stretches similar to the screen web of a roller blind or pleated curtain or an umbrella or parasol.
  • the SSPD preferably has one or more of: covers at least 2 or 5 metres seabed radially from the outer wall of the suction pile; covers a substantially rectangular or circular seabed area, preferably completely around the suction pile, e.g. without gaps or continuously, adjacent the suction pile; it, or part of it, slopes towards the seabed.
  • a plurality of SSPD's are provided circumferentially, possibly such that they partly overlap or connect side to side if unfolded.
  • the SSPD is constructed similar to an articulated awning, e.g. comprising a roll of sheet like cover material and one, two or more articulated arms that, by unfolding, move the free edge of the cover material away from the roll thus unrolling the cover material into an unfolded or stretched condition, wherein the roll and the one end of the articulated arm are fixed to the suction pile such that the roll can unwind and the articulated arm can pivot to extend or unfold.
  • the articulated arm carries out its extending movement in a plane substantially parallel to the plane of the unfolded part of the cover material, which plane is typically substantially horizontal (viewed in the upright condition of the suction pile).
  • the articulated arm has one or more, e.g. at least two or three, upright pivot axes, e.g. a pivot axis at one or both longitudinal ends and/or one remote from these ends.
  • An alternative to an articulated arm is a scissor like structure or a pantograph like structure.
  • Another alternative actuator to unfold the SSPD is a telescoping arm.
  • the web preferably has one or more of: comprises a woven or non woven fabric; heavy elements, e.g. rocks can be integrated, as a ballast means, e.g. in or along the web; a rough surface, e.g. artificial frond, to collect and retain sand from the seabed; is one or more of: pliable, flexible, wrinkable, rollable, foldable, preferably in a supple manner; can be folded and unfolded like a cloth; is a textile or textile like product; is a fibre like or fibre product; comprises pin or strip shaped elements, e.g. providing an artificial frond; it and/or the pin or strip shaped elements is made of rubber or rubber like material and/or has varying stiffness over its length.
  • heavy elements e.g. rocks can be integrated, as a ballast means, e.g. in or along the web
  • a rough surface e.g. artificial frond, to collect and retain sand from the seabed
  • the sheet like element e.g. can be rolled or folded, e.g. accordion like, in the retracted condition.
  • a preferred mat can be obtained with Seabed Scour Control Systems Ltd, Norfolk, (UK), sold as SSCS Frond Mat.
  • a SSPD preferably has one or more of: a preferably straight storage means to store the cover like device, e.g. rolled or pleated; at the leading edge of the cover like device a ballast means, e.g. a straight profile of e.g. metal; an actuator means, e.g. articulated arm, to move the leading edge, e.g. away from the storage means, to unfold the SSPD; if unfolded the cover like device is inclined.
  • a ballast means e.g. a straight profile of e.g. metal
  • an actuator means e.g. articulated arm
  • the length or height of the suction pile is the direction parallel to the direction of movement of the suction pile while it progressively penetrates the sea bed, thus the direction of the body axis or the direction from the top to the bottom.
  • the SSPD can have one or more of: a drive means, e.g. a spring or hydraulics, to drive the actuator means; a guiding means to guide the cover like device, which guiding means could be integrated with the actuator means; a tilting means allowing tilting of the SSPD to obtain the cover like device to slope towards the seabed, e.g. due to ballast means, or to positively tilt the SSPD by tilting drive means, e.g. hydraulic or mechanic, to obtain said slope.
  • a drive means e.g. a spring or hydraulics
  • the invention also relates to an SSPD with one or more of the following: designed for extension by an object separate from the SSPD, e.g. seabed contact, or by progressively penetration of the sea bed by the suction pile; has elongated elements, e.g. outrigger arms, which slide along the suction pile or make a translating movement during extension or unfolding of the SSPD; comprises rigid web carrying arms, e.g.
  • outrigger arms which in the extended state preferably extend radially from the suction pile or perpendicular to the length or height direction of the suction pile and preferably substantially horizontal or lying, and/or in the retracted state preferably extend substantially vertical or upright or parallel to the length or height direction of the suction pile; when moving from retracted to extended state the spacing between the ends of arms of it, e.g. distal from the suction pile, increases such that the to these arms mounted web preferably becomes unfolded and/or stretched; the web is mounted to arms at locations spaced along these arms; suspension arms the one end of which is pivotably mounted to the suction pile at fixed locations, the opposite end of which is pivotably mounted, e.g.
  • the one end of the outrigger arms is bifurcated or fork like and/or slide upward along the suction pile during unfolding the SSPD; the sliding movement is caused by the seabed, e.g.
  • the orientation of the outrigger arms changes from virtually vertical or upright to substantially horizontal or lying to extend radially from the suction pile;
  • the fixedly to the outrigger arms mounted foil unfolds in a way similar to the cloth of an unfolding umbrella or parasol and/or becomes stretched by the outrigger arms as soon as the SSPD arrives at its completely unfolded state;
  • the suspension arms slide with one end along the suction pile;
  • the preferably bifurcated end of the outrigger arms is pivotably mounted to the suction pile preferably at fixed location;
  • the suspension arms are forced by the relative movement between suction pile and seabed; gravity force and one or more of arms and hooking parts of the SSPD and/or suction pile keep the SSPD biased towards the folded or retracted state; gravity force and supporting means, e.g.
  • the sea bed bias the SSPD towards the extended state; completely separate from the suction pile, in other words no fixed connection; circumferentially encircles the suction pile, preferably completely; provides a partially, substantially or completely closed loop around the suction pile; has substantial form fit with the suction pile; can, preferably freely, translate lengthwise of the suction pile (thus vertically if the suction pile is oriented vertically as in operation); is retained in one or more translation directions, e.g. horizontally if in operation, different from vertical or upward; is kept retracted and/or retained from moving up or down along the suction pile by retaining means, preferably releasable, e.g. by hooking parts, e.g. at the SSPD (e.g.
  • hooks or eyes and/or the suction pile (e.g. hooks or eyes); hooking parts become disengaged as soon as the SSPD is moved, e.g upward or downward, e.g. due to further penetration of the suction pile into the seabed; hooking parts at the outrigger arms, preferably close to the remote ends, preferably engaging hooking parts at the suction pile, preferably close to the top; a hooking part, e.g. a hook, is disengaged, e.g. is lifted from a counter hooking part, e.g. an eye which preferably initiates unfolding or extending the SSPD; extending is provided since the, preferably initially vertically or upright oriented, arms, e.g.
  • outrigger arms pivot from the one to the second attitude, e.g. become horizontally or lying oriented and/or extend radially from the suction pile; arms, e.g. outrigger arms, pivot downward or upward, e.g. from upright or vertical to lying or horizontal or vice versa; arms, e.g. outrigger and/or suspension arms, pivot or swing, e.g. around a horizontal or lying axis; arms, e.g. the outrigger arms and/or suspension arms have a fixed length and/or rigid shape; arm ends sliding upward or downward along the suction pile are maintained in their mutual angular spacing by a means preferably proper to the SSPD, e.g.
  • the foil is stretched at the location of the one arm ends both in the retracted and extended state and/or at the opposite arm ends stretched if extended and unstretched, e.g. folded or loose if retracted;
  • the combination of SSPD and suction pile looks like an umbrella or parasol, and can be folded and unfolded as an umbrella or parasol, wherein de suction pile is functionally equivalent to the central pole of the umbrella; retaining means, e.g. at the suction pile, engage the SSPD and retain the SSPD from downward movement and allow its upward movement along the suction pile, or vice versa.
  • the unfolded SSPD surrounding the suction pile at a level between the open bottom and closed top, is suspended from hook members fixed to the suction pile in such a manner that with the suction pile in the upright attitude (longitudinal axis vertical, open bottom below closed top) the movement of the SSPD downward and/or outward (of at least the top edge of the SSPD) is retained by the hook members and upward is not retained by the hook members and sufficient upward movement causes that the SSPD becomes outside the retaining influence of the hook members such that the SSPD is released from the hook members to be no longer retained in downward and/or outward movement by the hook members, to move towards the unfoled position.
  • the hook members have a design to present a retaining edge having an outward radial extension from the suction pile (to retain downward movement of the SSPD) and/or an upward extension at a distance from the suction pile (to retain outward movement of the SSPD).
  • the outward radial extension projects from the suction pile and the upward extension connects to the end of the outward radial extension remote from the suction pile.
  • the SSPD is preferably provided with corresponding hook features to properly co operate with the hook members. During unhooking preferably the complete SSPD moves upward along the suction pile, counter to the gravity action.
  • the folded SSPD has a shape similar to a cylinder and the unfolded SSPD a shape similar to a disc with central hole, in both states the suction pile fits within the SSPD.
  • the folded SSPD has a first and a second edge close to the suction pile, while the unfolded SSPD has the first edge close to the suction pile and the second edge remote from the suction pile, preferably at least 1 or 2 meter further away compared to the folded state.
  • the SSPD is designed such that in the unfolded state the outer edge of the web properly connects to the seafloor to avoid scouring below the web, which in some cases allows that the web keeps a gap with the seafloor, however in other cases such gap is absent.
  • the web is present below the outrigger arms such that in the unfolded state the web is between these arms and the seafloor; the outrigger arms ends adjacent the web outer edge have a shape to promote that the web outer edge properly connects to the seafloor, e.g. a tapering shape and/or a downward curved flange; the thickness of the SSPD is smaller, e.g. at least 10% or 20%, at the outer edge away from the suction pile if unfolded compared to its thickness remote from this outer edge, e.g. the inner edge; in the unfolded state the web at the SSPD outer edge is closer to the seafloor, e.g.
  • the outward outrigger arm end has an element, e.g. flange, extending further longitudinally of the arm compared to another element of it, e.g.
  • the web which element preferably is angled or curved towards the seafloor; the web follows the shape of the outrigger arm, at least at the outward end; the web is ballasted or made heavier at the outer edge, e.g. by stones within e.g. a tube fixed to the web, to bias the web towards the seafloor.
  • the diameter of the suction pile is constant over its height (the height is the direction from the top bulkhead towards the opposite open end, which is the direction parallel to the suction pile longitudinal axis); from the top bulkhead the cylinder walls of the suction pile extend parallel; the open end of the suction pile, designed to be located on the sea floor first is completely open, in other words, its aperture is merely bordered by the cylinder walls; the water depth is such that the suction pile is completely below the water surface when its lower end contacts the sea floor, in other words when its lower end has not penetrated the sea floor yet; with the penetration of the suction pile into the sea floor completed, the top bulkhead is spaced from the sea floor.
  • the suction pile is also preferably provided with known as such valves and/or hatches adjacent or at its top bulkhead for selectively allowing water and air to enter or exit the suction space through the top side of the suction pile.
  • the arrow in fig. 4 and 7 indicates the direction of moving away the leading edge 4 from the storage 2.
  • the Fig. 9-22 embodiments are designed for extension by seabed contact and have elongated elements, e.g. outrigger arms, which slide along the suction pile or make a translating movement during extension or unfolding of the SSPD.
  • These embodiments preferably comprise rigid web carrying arms, e.g. outrigger arms, which in the extended state extend radially from the suction pile or perpendicular to the length or height direction of the suction pile and preferably substantially horizontal or lying, while in the retracted state extend substantially vertical or upright or parallel to the length or height direction of the suction pile (the length or height of the suction pile is the direction parallel to the direction of movement of the suction pile while it progressively penetrates the sea bed) .
  • the spacing between the ends of these arms distal from the suction pile preferably increases such that the to these arms mounted web becomes stretched.
  • the Fig. 9-12 embodiment has suspension arms the one end of which is pivotably mounted to the suction pile at fixed locations, the opposite end of which is pivotably mounted approximately midway between the ends of the outrigger arms which carry the foil.
  • the one end of the outrigger arms is bifurcated or fork like and slide upward along the suction pile during unfolding the SSPD, which sliding movement is caused by the seabed 10 while the distance between the top of the suction pile and the seabed decreases due to continued penetration of the suction pile during its installation.
  • the orientation of the outrigger arms changes from virtually vertical or upright to substantially horizontal or lying to extend radially from the suction pile.
  • Fig. 10 illustrates the changing level of the seabed relative to the suction pile top which forces the movement of parts of the SSPD which thus unfolds.
  • Fig. 13-16 embodiment applies roughly the same principle as with the Fig. 9-12 embodiment, this time however the suspension arms slide with one end along the suction pile while the bifurcated end of the outrigger arms is pivotably mounted to the suction pile at fixed location. The suspension arms are forced by the relative movement between suction pile and seabed (illustrated in Fig. 14 ).
  • the Fig. 17-22 embodiment applies an SSPD completely separate from the suction pile, in other words no fixed connection, however since the SSPD circumferentially encircles the suction pile, preferably completely and such that the SSPD provides a closed loop around the suction pile, as in the present embodiment, there is substantial form fit between the SSPD and the suction pile such that the SSPD can freely translate lengthwise of the suction pile (thus vertically if the suction pile is oriented vertically as in operation), however is retained in the other translation directions (thus horizontally if in operation).
  • the SSPD is kept retracted by hooking parts at the SSPD (hooks) and the suction pile (e.g.
  • Fig. 18 shows a sectional side view of Fig. 17 .
  • Fig. 19 shows a detail of Fig. 18 to illustrate that the hook 12 is lifted from the eye 11 and subsequently the initially vertically or upright oriented outrigger starts pivoting to become horizontally or lying oriented and extend radially from the suction pile. In this case the outrigger arm pivots downward, however upward pivoting from upright or vertical to lying or horizontal is also feasible.
  • the outrigger arms and suspension arms have a fixed length and rigid shape.
  • the arm ends sliding upward or downward along the suction pile are maintained in their mutual angular spacing by a means proper to the SSPD, e.g. provided by the foil which is preferably stretched at the location of these arm ends both in the retracted and extended state, or by an alongate element, e.g. a flexible pulling element, e.g. provided as a closed loop, or by rods connected to the arm ends.
  • Fig. 18-20 show a tapering shape of the outward end of the outrigger arms such that the web curves or angles downward to properly connect to the seafloor below, to avoid scouring below the web. Also shown is how the flange at the top of the outrigger arm extends outwardly beyond the outrigger arm web and angles or curves downward for said effect. The 30 degree angle is just an example. The height of the arm is typically 300 millimeter, thus the web above the arm is kept at a distance of 300 millimeter to the seafloor below.
  • Fig. 20 shows the outrigger arm in top and side view.
  • the invention is also directed to a separate SSPD for use with a suction pile and also relates to a method of scour protection by installing the suction pile into the sea bed and unfolding the SSPD such that its web covers the area around the suction pile.
